Keith Meisner said he hopes his tongue-in-cheek composition – Andy’s Gonnae Win Again – will help the Dunblane man relax.

The lyrics to his acoustic ditty go:

“Andy Murray can beat them all,

The greatest player to strike a baw,

Andy’s gonnae win again,

And hump them all at Wimbledon.”

The jingle also addresses Murray’s temper, as Keith sings:

“Some dinnae like him swearing,

Have no idea what it’s like,

How hard it is to keep the heid,

While playing total shi...”

Before the part-time tennis coach turns the air blue, he stops mid-sentence and says: “Audible obscenity, warning Mr Murray.”

Keith and Andy were rivals at junior level and the Elgin-born PE teacher keeps in touch with Andy’s brother Jamie.

He said: “It’s a bit of a laugh with a Scottish jig on it. We are, more or less, the same age and I played against Andy tons of times. I also played against his older brother Jamie a lot.

“I sent it to Jamie and he thought it was funny. He then shared it from his Twitter account.”

Keith admits he has no idea if Andy has heard the song but said he hoped it would give the 28-year-old some light relief during a stressful week.

He added: “It might give him a bit of a laugh.

“I think it’s incredible for Andy to be playing at the standard he is. He’s one of the best players of all time.”

It’s the second time Keith, who lives in Aberdeen, has penned a song for Andy. His previous Murray anthem, Under the Lights, got more than 63,500 hits on Keith’s YouTube channel and was shared with Andy’s 1.5million social media followers.
